Hello Karen
sorry for the message taking you by surprise.
our software is set up to recognize an active member from those who join to spam etc after a certain number of posts. So when you are still new and not yet at that post number you will not yet be able to post links, nor to edit in your profile. Sadly some spammers register on forums and use the signature and profile areas to do the spamming. they dont usually stick around after 10 posts
Members hopefully do
so....
